Description
Gegenstand der Erfindung ist eine Vorrichtung zum Besticken von flächenförmigem Nähgut gemäss Oberbegriff des Patentanspruchs 1.The invention relates to a device for embroidering sheet-like sewing material according to the preamble of claim 1.
Es ist bekannt, mit Nähmaschinen, insbesondere Haushaltnähmaschinen, Stickmuster zu erzeugen. Zu diesem Zweck wird das flächenförmige Nähgut, d.h. die Stickunterlage, in einen Stickrahmen eingespannt und der Stickrahmen wird von einem Antrieb, der den Stickrahmen in X- und Y-Richtung bewegen kann, entsprechend dem zu erzeugenden Stickmuster bewegt. Der Antrieb des Stickrahmens befindet sich in einem an den Freiarm der Nähmaschine andockbaren Gehäuse. Dieses ist an der Rückseite mit dem Freiarm und/oder Grundplatte durch eine Kupplung, welche die mechanische Verbindung bildet, verbunden. Der vom Antrieb bewegbare Stickrahmen weist üblicherweise eine Breite auf, welche etwa dem Abstand zwischen dem Nähmaschinenständer und der Nadel entspricht und eine Länge, die allenfalls das Doppelte der Breite ausmacht. Diese verhältnismässig kleine und durch die Gegebenheiten der Nähmaschine eingeschränkte Stickfläche eignet sich nicht für grössere zusammenhängende Stickmuster; sie ist vor allem bestimmt zum Sticken von Monogrammen oder Einzelsujets.
Bei Einzweck-Stickmaschinen und bei Spezialnähmaschinen, welche einen integrierten Antriebsteil für den Stickrahmen im Bereich des Maschinenständers aufweisen, ist es bekannt, Stickrahmen mit zwei oder vier Stickfeldern zu verwenden. Diese Stickrahmen weisen jeweils zwei nebeneinander liegende Rahmenkupplungen auf, mit denen der rechteckige Stickrahmen an zwei nebeneinander liegenden Punkten mit der Stickmaschine bzw. dem Stickrahmenantrieb verbunden werden kann; der quadratische Stickrahmen mit vier Stickfeldern weist vier Kupplungen auf und kann folglich an vier Stellen zur jeweiligen Bearbeitung eines Quadranten angekuppelt werden. Alternativ können die Aufnahmen auch stufenlos entlang des Stickrahmens verschieb- und einstellbar sein. Bei diesen Stickmaschinen sind die Stickrahmen-Antriebsorgane im Bereich des Maschinenständers, d.h. hinter der Nadel angeordnet. Dies ermöglicht das Ankuppeln grosser Stickrahmen, welche weit über die Nadel hinausragen.It is known to produce embroidery patterns with sewing machines, in particular household sewing machines. For this purpose, the sheet-like sewing material, ie the embroidery base, is clamped in an embroidery frame and the embroidery frame is moved by a drive which can move the embroidery frame in the X and Y directions in accordance with the embroidery pattern to be produced. The drive of the embroidery frame is located in a housing that can be docked onto the free arm of the sewing machine. This is connected at the back to the free arm and / or base plate by a coupling that forms the mechanical connection. The embroidery hoop that can be moved by the drive shows Usually a width that corresponds approximately to the distance between the sewing machine stand and the needle and a length that is at most twice the width. This relatively small embroidery area, which is limited by the conditions of the sewing machine, is not suitable for larger, coherent embroidery patterns; it is primarily intended for embroidering monograms or single subjects.
In single-purpose embroidery machines and in special sewing machines which have an integrated drive part for the embroidery frame in the area of the machine stand, it is known to use embroidery frames with two or four embroidery fields. These embroidery frames each have two adjacent frame couplings with which the rectangular embroidery frame can be connected to the embroidery machine or the embroidery frame drive at two adjacent points; the square embroidery hoop with four embroidery fields has four couplings and can therefore be coupled at four points for processing a quadrant. Alternatively, the recordings can also be moved and adjusted continuously along the embroidery frame. In these embroidery machines, the embroidery frame drive members are arranged in the area of the machine stand, ie behind the needle. This enables the coupling of large embroidery frames that protrude far beyond the needle.
Aus der EP-A2-0877112 ist eine Vorrichtung zum Besticken von rohrförmigem Nähgut bekannt, bei der die Stickvorrichtung, welche den Stickrahmen trägt und bewegt, beabstandet zum Unterarm der Nähmaschine liegt. Der dort beanspruchte Distanzhalter dient folglich dazu, den Spalt zwischen dem Sockel der Nähmaschine und der Stickvorrichtung 21 zu überbrücken und die Stickvorrichtung in der beabstandeten Position festzuhalten und die elektrischen Verbindungen sicherzustellen. Eine Verwendung mehrfach grosser Stickrahmen auf dieser Vorrichtung ist nicht möglich, da einerseits der zur Freilegung des Freiarms erzeugte Abstand sehr gering ist und andererseits, würde der Abstand vergrössert, der Stickrahmen keine Abstützung auf der Arbeits- und Nähfläche finden oder sogar sich in den Zwischenräumen verklemmen würde.From EP-A2-0877112 a device for embroidering tubular material is known, in which the embroidery device, which carries and moves the embroidery frame, is spaced apart from the forearm of the sewing machine. The spacer claimed there is therefore used to bridge the gap between the base of the sewing machine and the embroidery device 21 and to hold the embroidery device in the spaced-apart position and to ensure the electrical connections. It is not possible to use multi-sized embroidery frames on this device, because on the one hand the distance created to expose the free arm is very small and on the other hand, if the distance were increased, the embroidery frame would not find any support on the work and sewing surface or even get stuck in the spaces would.
Aufgabe der vorliegenden Erfindung ist die Schaffung eines Stickrahmenantriebs für Sockel- und Freiarm-Nähmaschinen, mit dem Stickrahmen mit ein- bis mehrfacher Normstickfläche angetrieben werden können.The object of the present invention is to provide an embroidery hoop drive for base and free arm sewing machines, with which embroidery hoops with one to multiple standard embroidery surfaces can be driven.
Gelöst wird diese Aufgabe durch eine Vorrichtung mit den Merkmalen des Patentanspruchs 1.This object is achieved by a device with the features of patent claim 1.
Die Zwischenschaltung eines Distanzadapters zwischen den Freiarm oder den Sockel der Nähmaschine und die Stickvorrichtung mit dem darin angeordneten Stickrahmenantrieb ermöglicht es, den zur Verfügung stehenden Raum zwischen der Nadelachse und dem Ständer der Nähmaschine, an welchem der Freiarm befestigt ist, in seiner vollen Grösse als Manövrierraum des Stickrahmens zu nutzen. In einer bevorzugten Ausgestaltung der Erfindung bildet die Zubehörbox, in welcher die Nähutensilien untergebracht werden können und welche, wenn keine engen rohrförmigen Teile bearbeitet werden, am Unterarm befestigt ist, den Distanzadapter. Es müssen folglich keine zusätzlichen Maschinenteile aufbewahrt oder zugekauft werden, um aus der Nähmaschine und einer Stickvorrichtung eine solche zu machen, mit der um ein mehrfaches grössere Stickflächen bearbeitet werden können.The interposition of a distance adapter between the free arm or the base of the sewing machine and the embroidery device with the embroidery frame drive arranged therein makes it possible to use the available space between the needle axis and the stand of the sewing machine to which the free arm is attached in its full size as a maneuvering space to use the embroidery hoop. In a preferred embodiment of the invention, the accessory box, in which the sewing utensils can be accommodated and which, if no narrow tubular parts are attached to the forearm, is attached to the distance adapter. As a result, no additional machine parts need to be stored or purchased in order to turn the sewing machine and an embroidery device into one that can be used to machine many times larger embroidery areas.

Die in Figur 1 dargestellte Freiarm-Nähmaschine 2 wird im einzelnen nicht näher erläutert, da deren Aufbau aus dem Stand der Technik hinlänglich bekannt und für den Erfindungsgegenstand unerheblich ist. Es werden zudem nur die für die Erläuterung der Erfindung notwendigen Teile der Nähmaschine 2 mit Bezugszeichen bezeichnet und näher erläutert. Im Unterschied zur Freiarm-Nähmaschine entfällt bei der Sockel-Nähmaschine der Freiraum unter der Arbeitsund Nähfläche. Als Arbeits- und Nähfläche dient dort eine Tischfläche, auf der der Ständer für den Oberarm aufgesetzt ist.The free-arm sewing machine 2 shown in FIG. 1 is not explained in detail, since its structure is sufficiently known from the prior art and is irrelevant to the subject matter of the invention. In addition, only the parts of the sewing machine 2 necessary for the explanation of the invention are designated by reference numerals and explained in more detail. In contrast to the free-arm sewing machine, there is no space under the work and sewing surface of the plinth sewing machine. A table surface on which the stand for the upper arm is placed serves as a work and sewing surface.
Mit dem Bezugszeichen 1 ist in den Figuren das Nähmaschinengehäuse bezeichnet, welches auf einer Grundplatte 5 aufgesetzt ist und eine im wesentlichen L-förmige Gestalt aufweist. Am vertikalen Ständer 4 des Maschinengehäuses 1 ist mit Abstand zur Grundplatte 5 der Freiarm 3 ausgebildet. In dessen freiem Ende ist, nicht sichtbar, unterhalb des Stichlochs 7 der Greifer antreibbar gelagert. Oberhalb des Stichlochs 7 ist an der Nadelstange 9 eine Nadel 11 eingesetzt. Auf der der Bedienungsperson zugekehrten Frontseite des Maschinengehäuses 1 ist ein Bildschirm 13 schematisch als Rechteck dargestellt. Alternativ könnte auch eine anders ausgebildete Anzeige- oder Bedienungseinheit vorgesehen werden. Ebenfalls am Maschinengehäuse 1 ist auf der gleichen Seite eine Rollkugel 15 vorgesehen. Die zugeordneten Betätigungstasten sind mit 16 bezeichnet. Eine weitere Tastenreihe 17 dient dazu, Sonderfunktionen anzuwählen. Sämtliche für die Fadenführung notwendigen Elemente und der Faden sind nicht dargestellt, weil sie für die Beschreibung der Erfindung und deren Verständnis nicht notwendig sind und deren Ausbildung auf die Erfindung keinen Einfluss hat.In the figures, the reference numeral 1 designates the sewing machine housing, which is placed on a base plate 5 and has an essentially L-shaped shape. The free arm 3 is formed on the vertical stand 4 of the machine housing 1 at a distance from the base plate 5. In its free end, the gripper is driven, not visible, below the tap hole 7. A needle 11 is inserted above the tap hole 7 on the needle bar 9. On the front side of the machine housing 1 facing the operator, a screen 13 is shown schematically as a rectangle. Alternatively, a differently designed display or control unit could also be provided. Also on the machine housing 1 is on the same side a track ball 15 is provided. The assigned actuation keys are designated 16. Another row of keys 17 is used to select special functions. All the elements necessary for the thread guide and the thread are not shown because they are not necessary for the description of the invention and its understanding and their design has no influence on the invention.
An das vordere Ende 19 des Freiarms 3 schliesst eine Stickvorrichtung 21 an. Letztere liegt auch satt an der Rückseite 23 des Freiarms 3 an und ist durch nicht dargestellte Kupplungsmittel mit der Maschine 2 mechanisch verbunden. Auf der Stickvorrichtung 21 ist ein Stickrahmenträger 25 in X-Richtung antreibbar gelagert. Am Stickrahmenträger 25 ist weiter in Y-Richtung verfahrbar ein Stickrahmen 27 befestigt. Eine mögliche Ausbildung der Antriebsorgane für den Stickrahmen 27 ist im Deutschen Gebrauchsmuster 29614512 Ul beschrieben. Verschiedene weiter Antriebsmittel für die X-/Y-Bewegungen eines Stickrahmens sind aus dem Stand der Technik hinlänglich bekannt und werden daher nicht im Detail erläutert. Durch eine entsprechend ausgebildete, nicht näher beschriebene oder dargestellte Steuerung kann der Stickrahmen 27 in bekannter Weise auf einer programmierbaren Bahn verfahren werden. Dementsprechend können mit der Nähmaschine 2 freiprogrammierbare Muster auf einem textilen Gebilde, das im Stickrahmen 27 eingespannt ist, erzeugt werden. Die gegenseitige Lage zwischen der Stickvorrichtung 21 und dem Freiarm 3 der Nähmaschine 2, wie sie in den Figuren 1 bis 3 dargestellt ist, entspricht dem Stand der Technik.An embroidery device 21 connects to the front end 19 of the free arm 3. The latter also abuts the back 23 of the free arm 3 and is mechanically connected to the machine 2 by coupling means, not shown. On the embroidery device 21, an embroidery frame carrier 25 is mounted so that it can be driven in the X direction. An embroidery frame 27 is attached to the embroidery frame carrier 25 so as to be movable in the Y direction. A possible design of the drive elements for the embroidery frame 27 is described in German utility model 29614512 Ul. Various other drive means for the X / Y movements of an embroidery frame are well known from the prior art and are therefore not explained in detail. The embroidery frame 27 can be moved in a known manner on a programmable path by means of a correspondingly designed control, not described or shown in detail. Accordingly, with the sewing machine 2 freely programmable patterns on a textile structure that is clamped in the hoop 27 are generated. The mutual position between the embroidery device 21 and the free arm 3 of the sewing machine 2, as shown in Figures 1 to 3, corresponds to the prior art.
In den schematischen Darstellungen in den Figuren 4 bis 11 sind nur noch die für die Erfindung wesentlichen Teile bzw. die Umrisse der Nähmaschine 2 und der Stickvorrichtung 21 dargestellt.In the schematic representations in FIGS. 4 to 11, only the parts essential for the invention or the outlines of the sewing machine 2 and the embroidery device 21 are shown.
In Figur 4, welche die erfinderischen Merkmale aufweist, ist nun zwischen die Stickvorrichtung 21 und den Freiarm 3 ein Distanzadapter 29 eingesetzt, welcher bewirkt, dass die Stickvorrichtung 21 in Längsrichtung des Freiarms 3, d.h. in X-Richtung beabstandet vor der Nähmaschine 1 zu liegen kommt. Diese Verschiebung um den Betrag R1 erlaubt es, einen Stickrahmen 27 von doppelter Kantenlänge wie derjenige in Figur 2 auf die Stickvorrichtung 21 aufzusetzen. Die Nadel 11 kann bei dieser Stellung bis in der Mitte der Stickfläche innerhalb des Stickrahmens 27 einstechen und, in Y-Richtung gesehen, den gesamten Quadranten A bearbeiten. Der Stickrahmen 27 ist für die Bearbeitung des ersten Quadranten "A" an der Stelle KI durch eine Rahmenkupplung 28 mit der Stickvorrichtung verbunden (Figur 7). Für die Bearbeitung des zweiten Quadranten "B" wird der Stickrahmen 27 an der Stelle KII befestigt (Figur 8). Dadurch ergibt sich eine Verschiebung des Stickrahmens 27 in Y-Richtung. Figur 9 zeigt die Situation, in welcher der Stickrahmen 27 um 180° um dessen Zentrum gedreht ist und die Bearbeitung des dritten Quadranten "C" erfolgt. Nun ist der Stickrahmen 27 an der Befestigungs- oder Kupplungsstelle KIII mit der Stickvorrichtung 21 verbunden. Zur Bearbeitung des vierten Quadranten "D" erfolgt die Verbindung des Stickrahmens 21 an der Stelle KIV (Figur 10). Die Justierung des Stickrahmens 27 unter der Nadel 11 nach dem Umkuppeln erfolgt auf elektronischem Weg durch die Steuerung oder durch eine mechanische Justage.In FIG. 4, which has the inventive features, a spacer adapter 29 is now inserted between the embroidery device 21 and the free arm 3, which causes the embroidery device 21 to lie in front of the sewing machine 1 in the longitudinal direction of the free arm 3, ie in the X direction comes. This shift by the amount R1 makes it possible to place an embroidery frame 27 of twice the edge length as that in FIG. 2 on the embroidery device 21. In this position, the needle 11 can penetrate into the middle of the embroidery area within the embroidery frame 27 and, viewed in the Y direction, machine the entire quadrant A. The embroidery frame 27 is connected to the embroidery device for processing the first quadrant "A" at the point K I by a frame coupling 28 (FIG. 7). For the processing of the second quadrant "B", the embroidery frame 27 is attached at the point K II (FIG. 8). This results in a shift of the embroidery frame 27 in the Y direction. FIG. 9 shows the situation in which the embroidery frame 27 is rotated by 180 ° around its center and the third quadrant “C” is processed. The embroidery frame 27 is now connected to the embroidery device 21 at the fastening or coupling point K III . To process the fourth quadrant "D", the embroidery frame 21 is connected at the point K IV (FIG. 10). The adjustment of the embroidery frame 27 under the needle 11 after the coupling is done electronically by the control or by a mechanical adjustment.
In der Ausgestaltung der Erfindung gemäss Figur 5 wird die Stickvorrichtung 21 durch den Distanzadapter 29 in X-Richtung um den Betrag R2 vom Freiarm 3 entfernt befestigt. Es besteht nun kein direkter Kontakt zwischen der Stickvorrichtung 21 und dem Freiarm 3. Der Distanzadapter 29 umfasst den Freiarm 3 auf drei Seiten. Durch diesen zusätzlichen seitlichen Abstand kann ein entsprechend noch grösserer Stickrahmen 27 verwendet werden.In the embodiment of the invention according to FIG. 5, the embroidery device 21 is fastened by the distance adapter 29 in the X direction by the amount R 2 from the free arm 3. There is now no direct contact between the embroidery device 21 and the free arm 3. The distance adapter 29 comprises the free arm 3 on three sides. Due to this additional lateral distance, a correspondingly larger embroidery frame 27 can be used.
In der Ausgestaltung der Erfindung nach Figur 6 erfolgt sowohl eine Distanzierung der Stickvorrichtung 21 vom Freiarm 3 sowohl in X- als auch in Y-Richtung um die Beträge R1 und S1.In the embodiment of the invention according to FIG. 6, the embroidery device 21 is distanced from the free arm 3 both in the X and Y directions by the amounts R 1 and S 1 .
Der Distanzadapter 29 wird mittels ersten Kupplungsmitteln am Freiarm 3 und/oder an der Grundplatte und mittels zweiten Kupplungsmitteln mit der Stickvorrichtung 21 vorzugweise formschlüssig verbunden. Die beiden Kupplungsmittel sind nicht sichtbar. Die Energiezufuhr für die Antriebe in der Stickvorrichtung 21 kann durch die besagten Kupplungsmittel oder über ein Kabel der Stickvorrichtung 21 erfolgen.The distance adapter 29 is preferably connected to the embroidery device 21 by means of first coupling means on the free arm 3 and / or on the base plate and by means of second coupling means. The two coupling means are not visible. The energy supply for the drives in the embroidery device 21 can take place through said coupling means or via a cable of the embroidery device 21.
In einer besonders vorteilhaften Ausgestaltung der Erfindung dient der Distanzadapter 29 gleichzeitig als Zubehörbox, bzw. die üblicherweise mit der Nähmaschine 2 gelieferte Zubehörbox, deren Oberfläche - verbunden mit dem Freiarm 3 - die Nähfläche vergrössert, dient als Distanzadapter 29. Auf diese Weise muss einzig die Zubehörbox mit den Kupplungsmitteln für die Stickvorrichtung bestückt werden bzw. der Distanzadapter 29 muss einen Deckel, eine Schub- oder eine Drehlade aufweisen und im Innern die entsprechenden Halterungen für die Zubehörteile enthalten.In a particularly advantageous embodiment of the invention, the distance adapter 29 also serves as an accessory box, or the accessory box usually supplied with the sewing machine 2, the surface of which - connected to the free arm 3 - increases the sewing area, serves as a distance adapter 29. In this way, only the Accessory box with the coupling means for the embroidery device or the distance adapter 29 must have a lid, a drawer or a rotating drawer and contain the corresponding holders for the accessories inside.
In Figur 11 liegt die Stickvorrichtung auf einer seitlich am Distanzadapter 29 angeordneten Aufnahmeplatte 29'.
